The role of a structure directing agent tetramethylamonium template in the initial step of silicate oligomerization in aqueous solution

01-Jul-2015 | Thuat T Trinh; Khanh-Quang Tran; Xue-Qing Zhang; Rutger A van Santen; Evert Jan Meijer, Physical Chemistry Chemical Physics, 2015

To understand the formation of silicate oligomer in the initial stage is a key for zeolite synthesis. The use of different organic structure directing agents is known to be a key factor in the formation of different silicate species and the final zeolite structure. Tetramethylammonium (TMA+), for ...

28-Jun-2015 | Author(s): Setareh Monshi Toussi , Marco Zanella , Gaser Nagah Abdelrasoul , Athanassia Athanassiou , Francesca ..., Journal of Photochemistry and Photobiology A: Chemistry, 2015

Publication date: 1 October 2015 Source:Journal of Photochemistry and Photobiology A: Chemistry, Volume 311 Author(s): Setareh Monshi Toussi , Marco Zanella , Gaser Nagah Abdelrasoul , Athanassia Athanassiou , Francesca Pignatelli Synthesis of gold nanorods by photochemical reduction ...


Influence of the Metal Work Function on the Photocatalytic Properties of TiO2 Layers on Metals

26-Jun-2015 | Janna Freitag, Detlef W. Bahnemann, ChemPhysChem, 2015

Abstract The photocatalytic properties of titanium dioxide (TiO2) layers on different metal plates are investigated. The metal–semiconductor interface can be described as a Schottky contact, and is part of a depletion layer for the majority carriers in the semiconductor. Many researchers have ...


Experimental survey of the kinetics of acene Diels–Alder reactions

26-Jun-2015 | Brittni A. Qualizza, Jacob W. Ciszek, Journal of Physical Organic Chemistry, 2015

Second‐order rate constants were gathered for solution Diels–Alder reactions of substituted and unsubstituted acenes, with the intention of ascertaining ideal diene–dienophile combinations. Particular focus was placed on the larger ring systems namely tetracene, pentacene, and rubrene. The rate ...


Oxidation of neodymium precipitates in a Ti6Al4V2Nd alloy in sodium chloride solution

26-Jun-2015 | F. Depentori, C. Forcellini, F. Andreatta, E. Marin, S. Maschio, F. Brunke, S. Benfer, C. Siemers, L. Fedrizzi, W. F ..., Materials and Corrosion, 2015

The corrosion properties of a neodymium modified titanium alloy, Ti6Al4V2Nd were investigated in 1.5 wt% NaCl and compared with Ti6Al4V. The modified alloy contains neodymium precipitates mainly located at grain boundaries. Ti6Al4V2Nd differs in corrosion behavior from Ti6Al4V by the oxidation ...


Structural properties and chemical bonds in double metal cyanide catalysts

26-Jun-2015 | K. Lawniczak‐Jablonska, E. Dynowska, W. Lisowski, J. W. Sobczak, A. Chruściel, W. Hreczuch, J. Libera, A. Reszka, X-Ray Spectrometry, 2015

Double metal cyanide (DMC) catalysts are commonly applied at industrial ring‐opening polymerization of the epoxides, being the initial stage of the polyurethanes manufacturing route. This group of catalysts is frequently used in industry, but the knowledge on the molecular nature of their high ...


Low-Impurity High-Performance Solution-Processed Metal Oxide Semiconductors via a Facile Redox Reaction

26-Jun-2015 | Huajun Chen; You Seung Rim; Chengyang Jiang; Yang Yang, Chemistry of Materials, 2015

Metal oxide semiconductors realized using solution processes have received a great deal of attention because of their low cost and simple fabrication. One major problem associated with the solution approach is the presence of undesired impurity species introduced by precursor solutions. Here, we ...


Charged supramolecular assemblies of surfactant molecules in gas phase

26-Jun-2015 | David Bongiorno, Leopoldo Ceraulo, Sergio Indelicato, Vincenzo Turco Liveri, Serena Indelicato, Mass Spectrometry Reviews, 2015

Abstract The aim of this review is to critically analyze recent literature on charged supramolecular assemblies formed by surfactant molecules in gas phase. Apart our specific interest on this research area, the stimuli to undertake the task arise from the widespread theoretical and ...


Facile preparation of asymmetric Ni/PVC film with controlled structure: Application as a high‐performance EMI shielding material

24-Jun-2015 | Yang Zhang, Xiaoxia Fang, Bianying Wen, Wenqi Zou, Journal of Applied Polymer Science, 2015

ABSTRACT Controlling the spatial configuration of conductive fillers in thin composites by a facile strategy is critical to widely commercial use these materials for electromagnetic interference (EMI) shielding applications. In this work, a series of free‐standing thin Ni/polyvinyl chloride ...


First Evidence of Rh Nano-Hydride Formation at Low Pressure

24-Jun-2015 | Claudia Zlotea; Yassine Oumellal; Mariem Msakni; Julie Bourgon; Stéphane Bastide; Christine Cachet-Vivier; Michel La ..., Nano Letters, 2015

Rh-based nanoparticles supported on a porous carbon host were prepared with tunable average sizes ranging from 1.3 to 3.0 nm. Depending on the vacuum or hydrogen environment during thermal treatment, either Rh metal or hydride is formed at nanoscale, respectively. In contrast to bulk Rh that can ...
